Total eclipse of the Sun, Cornwall, 1999
I unexpectedly got a last minute seat on a plane that was due to fly along the south coast of Cornwall and into the path of the umbral shadow. Being unprepared for this I had to improvise with what I had. I used my Canon F1n, a 200mm f2.8 lens and a polarising filer. I fitted the filter in the hope that it might reduce the solar glare, stopped the lens right down, set a high shutter speed and removed the AE prism.
I pointed the camera up through the plane's window and looking down at the focusing screen, Fired off about ten shots at a variety of shutter speeds before the reappearing sun got too bright. The camera was unharmed but when the slides came back the film had been slightly buckled by the heat of the reappearing sun. I only got one good image. Agfa CT100 film. This method is definitely NOT recommended. There is a longer account of this event on the Astro page.
